ToALL WHoM IT MAY ooNcERN:

Be it known that I, LEWIS COSLER, of Yellow Springs, Greene county, and State of Ohio, have invented an fImproved Thresher for Threshing'and Separating- Grain, Clover', Flan, 85e.; and I hereby'declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a side elevation,

Figure 2 a longitudinal section, and

Figure 3 an end view of the threshing-machine.

Figure 4 represents the cylinder and concave, with their teeth for hull'ingand cleaningthe grain.

Figure 5, the double conveyers, for discharging the grain, s'eed, bolls, and sticks, at the outside of thc machine.

The nature of my invention consists in the construction of the revolving beater on top of the apron.

Also, thc adjusting-screws, for tightening or sla-ckening the belts.

Also, the extension-sieve, into which the seed that has been blown forward falls and is sieved.

Also, the shape and construction of the slats' or buckets of the lower apron.

Also, the incline-shapedthroat, through which thc grain falls from the lower apron or belt.

Also, the conveyers, for discharging the grain, seed, die., at the side of the machine.

A represents the frame that supports the devices of the machine.

B B, the belt and pulley-gearing that drives the devices.

C, the cylinder and concave for hulling and cleaning the grain.

D is a smooth concave that is used instead of the tooth concave C when required for cleaning the seed.

E is the fan, driven by the bevel-gearing Gr.

H is the upper apron or carrier, that travels around rollers, J, and carries -the grain, flax, &c.,vup its incline ,as it leaves the cylinder C.

K is the lower apron or carrier, that conveys thevgrain to the throat L, from whence it is conveyed to the shoe to be fanned and sieved.

M are adjustable armsat each end ofthe rollers J, that operate in boxes on each side of the frame, for the purpose of slackening or tighteningl the aprons up or down, back or forward, whenever required, whilst the machine is in operation and the aprons are running, andas the arms M are adjusted, they are fastened by a thumb-screw, N, to their places. I

The slats or buckets that form the lower apron, tit flat and close together, and open as they passover the roller at the throat L,- so that the grain and seed are easily discharged, and none retainedin the buckets, but they form a close apron in operation, so that no grain collects or chokes upon its way to the throat to be dischargedA The upper apron, H, carrying olf the straw, and the lower apron, K, the grain or seed as they fall through the concaves C or D, or separator-bars below the cylinder C.

The slats that form the lower apron, K, are made of wood, concave on the lower side, and straight above, so that their concave sides conform with the cylindrical shape of the rollers J, and, therefore, move easily and smoothly around the roll-ers. i

i The throat L has an incline-shaped drop or offset, so that the grain or seed falls down rapidly, and docs not choke the apron K. i

P is the beater, with its circular end plates revolving in close grooves in' the frame A, to prevent the tangling of the iiaX or chokingit up as the seed is being knocked out by the beater, whilst the flanges Q push forward the iiax or straw upon the apron H. The flanges are made of wood, and fit closely at their axis.

rEhe conveycrs R and S operate horizontally, side by side. The one conveyer, R, nearest to the fan E, discharges the bells and sticks, the other conveyer, S, discharges thc clean seed as it falls `through the sieve T, and when I clean grain the cockie and cheat fall also through the sieve T, whilst the grain passes over to the other conveyer,'lR, at the side, reversing the action, because the end of the sieve projects only as far as the centre between the conveyers R'and S. l i i U is the extension-sieve at the outer end of the shoe Y, that is a double sieve, the top being level, and the lower sieve being on an incline to the side," so as to catch and 'collectthe seed that has been' blown forward by the fan, upon which it falls andj's sieved, ,and then collected in a box or halfbushel measure, and again carried forward by the operatorto the cylinder C Ain front to beagaimcleaned.

As the grain falls frorn the throat L'itlisilfannedand si'evd in the `vihratingshoe V by 'the common fun i E and sieves W, X, and l.

Y is the common elevator for reconveyingthe grain tothezcylinder in front, to bcclean`ed again. Z is the crank or driving-wheel, by which 'the machine is driven. 'I What vl2 claim as my invention, and desire to secure by Letters Patent, is V 1. The adjustable arms M, as herein set forth. i l i 2. I also claim the extension-sieve U, for the purpose set forth.

3. I also claiuithe construction voithe incline-shaped throat L, when located at thetoi) of the apron K, asl

herein'descrihedand for the purposes set forth.

4. I also claim the arrangement ot" the two conveyers R and S, when located and operating with the sieve T, as described and set forth.
